Description
These visible-light objective lenses deliver diffraction-limited performance across the entire visible spectrum. Their advanced multi-element optical design, combined with optimized coatings and infinity correction, minimizes aberrations while maximizing optical transmission for exceptional image quality.The lenses feature a darkfield optical configuration that enables coaxial darkfield illumination, making them well suited for high-contrast imaging and inspection applications.
Thanks to their long working distance and infinity-corrected design, these objective lenses can also be integrated into laser systems for coaxial observation and visible laser focusing. They enable precise microscopic observation and laser focusing from a comfortable working distance.
Key technical features include:
- High numerical aperture (NA) for high-resolution imaging and fine detail capture
- Chromatic aberration correction for accurate color reproduction and minimized color fringing
- Standard RMS threading for compatibility with conventional microscopes and optical mounts
These objective lenses are ideal for applications in microscopy, machine vision, laser systems, and precision optical inspection where superior resolution and image quality are critical.
